This Dump Truck is a "Green Can O' Worms" that shouldn't have been opened!!! 

I love those regen systems they can be so hard to figure out they will have you wondering why your a mechanic in the first place 😂

Dump trucks see some of the hardest driving any vehicle ever sees.

Yeah, living in a rusty climate I can tell you that a lot of problems come from poor grounds. I spent two days beating my head against the wall when my wife's car wouldn't crank after having replaced an alternator. Turns out the ground strap from the block to the body didn't have any continuity, despite looking like it was in ok shape, just the fact that I touched it was all it needed to fail, but like you said, I spent forever tracing wires, figuring out circuits, ect. I was mad beyond words.

It’s maddening to see the damage that the DOT’s road salt and magnesium chloride is causing on vehicles wiring, frames, body panels, etc. etc.

I thought that piston in the Destruction of the Week was an u-joint at first.... Love watching your videos, always learn something new even thought I've never worked on any diesel (yet).

I have a truck with the same engine and I have had all the exact same problems. I had to take my truck to the CAT Doctor in Fontana, CA and he fixed it very good. I don't have any problems now.

Pretty great troubleshooting and diagnosis vid Josh. Thank you for the shout out. Learned alot. Cheers man happy wrenching.🔧🔩💪👍

Another electrical point to check on Peterbilts is the ground wire to the cab near the left front cab mount, have come across many issues with gauges and switches not working correct, and other things, check both ends as it comes from the starter. I had a disc made to install on the low psi turbo on the acerts that I can supply regulated air to the intake system and have found lots of leaks that way the same as you did there. All the SDP have been deleted around my area... thank god.

Appreciate you telling how far to fast forward to skip the technical portion 👍

Ahh, good old Cat ET data logging!! Invaluable at times! Solved quite a few 3500 series genset issues with it.

I'm so glad I'm retired. That truck looks like it's been around the salty ocean air for quite awhile. You get that kind of rust and crust from the salt filled sand.

Great video. I am not a diesel mechanic or a real mechanic. I am just a home gamer who tries to help people out. That said, anyone who leaves zip ties like that is on the same level as people who throw dirty diapers in the parking lot. I appreciate the in-depth run-throughs. Added knowledge helps down the road. Take care and happy hunting!

Interesting!! Even tho I'm not a diesel mechanic, (electrician, Maintenance Tech) I really enjoy your videos! The way you go to trouble shoot the problems! Stay safe!! Looking forward for Part 2!!

Bro, you are very patient, I respect you. Keep up the good work you are doing. Look forward to part 2.

Rust and corrosion very typical to what we see here in New England and the northeast in general, because of the salt and other corrosive chemicals they put on the roads in the winter.

Your information on CAT engine is great! I had a 6.6 CAT in a swather giving me fits on starting issues. I watched your videos and got some great information! I was able to to eliminate alot of things but ended up calling a CAT dealer to hook up his EST to read ECM. Thank you!

Funny how the video makes it look easy to diagnose but it’s not. Good job

Impressive,if frustrating work. Looking forward to part 2.

Welcome to Michigan!!! Everything here is a rust bucket and corrosion is by far the biggest cause of failure behind driver stupidity.

Just went down the same road. Found a ton of boost leaks and my secondary air was still low after all my repairs. The plug on the bottom of the intake elbow was missing, thought forsure that was my problem. I atleast had ignition on the truck i was working on. A badly plugged dpf will cause low air flow. Ran the air test with the dpf disconnected and my air test results were good

I had a truck (Freightliner with Mercedes OM460) that was brand new. The truck had sat around for years. It needed a wet kit and fith wheel among other things. One day i started the truck. It started and ran fine but there was no throttle response. I cleaned every electircal connection i could find. Nothing looked problematic. The same, no throttle response. I came back to it a month later. I cleaned all the battery and ground connections again. It stared and the throttle worked fine. I have never had another issue with the throttle. It demonstrates how inportant the correct voltage is for the electronic.

This is a very informative video thank you so much for sharing.

Love your philosophy. Basically “ if you can’t get out of it, get into it”

Kind of a PIA to set up but a smoke machines shows a lot pretty quick. Liked the log file playback. I don’t think that was in your Regen video which I did watch some time ago. Helped me bigly on C7 regen issue in a bus. Sent a donation.

when working on a ard head engine the first thing you should do is ohm the glow plug, if its not good then a new ard head is needed, its not in the troubleshooting tree, fuse and filter fittings is, if the glow plug is bad it cant cook the soot out of the head and it plugs up and will never light

Bought a Costco size box of Baking Soda years ago and have a spray bottle with solution in it to deal with corrosion on battery terminals. Surprised how many Techs don't inspect or clean Battery terminals or connections. Not on the Approved by Customer list to fix I guess.

In New England MA I have had the luxury of being able to remove valve covers with prybars, its much easier than trying to remove the bolts. Most of the time they snap right off and the end exposed to the engine oil can just be removed later with some vice grips.

Great video! Thank you for sharing the knowledge

This video right here shows EXACTLY why I HATE allen head bolts! The middle of this video is pure pain.

If I remember that movie correctly, Arnold says "wrong" and then shoots the guy who kidnapped his daughter. I think it would have been hilarious to put that second part in there, so it's like Arnold is shooting people who think it's cool to put silicone where it doesn't go. Great video though.

Great job! Thank you very much

Use salt on the roads they said... It'll be good for the cars they said.

Amazing diagnostics 👍

Great stuff! you are not afraid of problems!

I worked with little cars and the data (CANs). Found this very interesting

Lord , am I ever glad I never had to deal with those DPF's . Mine was a'07 Pete with an "06 C13 ACERT. No DPF ,no EGR, no DEF.

I am not seeing enough air leeks to make up for the differential pressure loss, Will be interesting to see if that was the problem.

Excellent video! A ton of good information.

As if ACERTS weren’t problematic enough… regen! 😳 {Shivers}

3406b for the win, give me a glider so equipped.

Glad the ECM bolts worked out, took a few try's to find the right lock and bolt. Silicone Sam strikes again. On the Combustion Air Valve you have a port on top and you have one in the front. These are air ports. I made a setup that I screw a test boost sensor in and wire it up to the boost connector. I then run a ASVT and get a reading on turbo side vs inlet manifold side. Have seen the CAC plug up. Quick way to check both sides. Have you ever ran a ARD override test? I like it at 1500 RPM's. I have not been able to find the other side of the connector for the ECM, 120 pin. On 70 and 40 pins, I made bypass harness's. That way I can take the connectors off and hook my test ECM up and not pull the ECM until I know it needs to be replaced. I had one that I tried this test. The pilot was stopped up in the ARD head. So I took the fuel lines off at the ARD head, tied them together and plumbed both lines into the main port. Ran a ignition test and it ignited. Logged a fuel psi fault as pilot psi was reading main. But I verified pilot nozzle was plugged up in the ARD head. If I get a FTI or LOC at the start, I run the ARD heater nozzle test back to back three times. Let it time out, I think it last three minutes each. I then try an ignition test again. If it won't ignite, your wasting your time trying a one hour heat cycle test. When these darn things first came out. I was put on one after several people had tried fixing it. You name it and it was replaced on the REGEN system. It was in a FLT and I ran a ground wire from battery negative to cab and to ground stud on head. It would REGEN with the external wire on. Take it off and engine would not REGEN and sometimes it had a hick up and all REGEN temps went to 32F. I am sure you have seen the DPF so plugged up, you have to take it off and clean it out, so you can get a REGEN started. Good luck, keep me posted. I like to learn on these darn things as they get older who knows what you will find.

Some times you just got to fix other problems before you can fix why it's in the shop in the first place.

It almost looks like that trucks been in New York a lot. They sprayed deicer on the ground and it rusts everything.

I love hunting green wire. I work at an automotive electrical shop.

I run an 09 t800 with a c13 regen engine. Almost a million miles with an inframe at 660k. One thing ive learned with this truck is that when things are going wrong and nothing makes any sense, its almost always the ard head. Took it to the kw dealer 3 times, and they replaced sensors because the computer told them thats what was wrong. 100 miles down, its back, regen light and a derate. Finally got it to a cat dealer. 3 hrs later and a phone call, yep, ard heads bad. Never fails, once every 12 to 18 months, ard head goes. Other than that, she runs like a top. I'll deal with that over having all the problems with def systems. One wayi found to keep her running good is to switch out a new primary fuel filter evey 6k. If i dont, get a check engine light simply because the fuel pressure drops off just enough it cant regen.

Awesome video. You explain things very well!! 👍👍👍

Good information Very interesting to see whole system failures. Boy I hate salt. I don’t think I’ll ever get to work that cat engine.

They make a nifty tool for cable ties it tensions them and cuts when done. tension can be adjusted as well. They are available at electronics stores.

When you come across the next corrosion problem on a battery/cable and it's a bugger to clean, pour some boiling water on it, i just use an electric kettle/jug as it holds a bit and pours easily. And a lot of times that I've come across those v band clamps loose because the previous "makanik" has tightened the nut only without tapping the band around its circumference seating it properly.

Nice work !

Regen says it all

19.06 breadsoda and boiling water cleans them up like new

cat ECM plugs are pretty damn good at sealing out corrosion but lucky you took it out to check anyway, probably knocked the positive lug off while you were in there. better it breaks off when you're already in the shop.

I forgot, any time I replace a harness. I get the old bolt out of the connector. Sometimes I bust the connector open and get the bolt and lock. I then try to take the lock off. Or I cut the allen head off if the bolt is damaged and slide the lock off. And last I just drive the bolt out and sometimes the lock is not damaged.

I am merely an amateur (on cars) but so far undefeated with my Irwin shoulder extractors (14:09). The key is not to bottom it out. The hole has to be deep enough.

You touched it now it's yours! 💩👀😂

Something sketchy about that middle battery

this would be a good opportunity for a single turbo conversion

No vehicle maintenance means nite mare's for the mechanic tech. How you guys work on this crap nowadays is a miracle I'd come to work with a half gallon of whiskey ronrdzl

You need to pick up some Mac RBRT bits they are amazing

Baking soda and water and initialize all the acid comes battery keep it from turning green again live in Michigan so I see a lot of rust that doesn't surprise me

The zip tie thing is a huge pet peeve of mine. I can’t tell you how many cuss words I’ve said over being cut by them. Olympian standby gen sets were the worst. They would come from the factory with 100’s of them in the panel. If someone won’t use a tie wrap gun around me I won’t let them work on my jobs.

Use a torx bit all fails or Mac rbt off for Allen keys works all the time for me

Yeah that truck has definitely been on a salty road and not wash down after use over the course of many years I’m not judging I don’t know the operator or business owns it’s financials but I do know that cleaning your vehicle routinely saves you in the long run a lot of money and heartache

Apparently this feller likes tailgating the salt trucks in winter 😅

Looks like it spent some time at a Potash mine!!!

Sure do miss the music for The Destruction of the Week intro.

G'day mate, Try bicarbonate of soda in hot water to neutralize the acid on the battery terminals. cheers. Butch.

Rust is because it is a garbage truck, and lives in the dumpsite, and will never be cleaned under the chassis, as about the only thing that might be washed is the windscreen, once you can not see through it.

I'm not a big truck mechanic but I'm a mechanic in wisconsin and hate coming across vehicles like this when it's so crusty and it's just not stop. Yeah it's makes you money, but I just get sick of the same car lol

It may work on this application, but to remove stripped Allen bolts, a dab of medium valve grinding compound smeared in the hex hole in the Allen bolt will allow the bit to gain purchase and remove the fastener.....most of the time.

Josh I love the technical stuff but please get OBS studio (it's free) and record your screen instead of trying to do it with your gopro. Thanks for the great content as always!

Wow been to previous mechanics none checked something simple like dirty battery cables

Maybe someone should have been getting the engine steamed off once in awhile.

While half of america is watching videos about the Kardashians I'm over here learning about how Cats aftertreatment works. I win

What your thoughts on using grease on battery cable connections to keep corosion down

I love the goat. Every time 😂

As much as I care for people's health, I still think that the EPA are being way too strict when it comes to Diesel emissions.

Would silicone dielectric grease be a good idea on the battery terminals to prevent future corrosion?

Is the truck used to salt the roads in winter ❄️?

Screen door in the system..😂😂😂

The state of that tire is telling.

I'm surprised that stuff hasn't found it's way into a dumpster years ago.

Those rounded fasteners make me glad I'm not paid flat rate.

Josh, have you ever used loadpro test leads?

Looks like truck from oh canada

What kind of truck is that because from looking at the hood it almost looks like a 386

What ended up happening with the trash fire international?

What do you use for corrosion inhibitor?

You wanna talk about a can of worms? Jeebus, Have I got into a good one now! Machine is a 583K pipelayer, which is a D8K crawler modified for laying pipelines. This one had a Fan blade come out of the hub, which in turn jammed into the other blades and destroyed everything up front and busted the front cover of the Engine. (Its a D342) this lead to a gong show to get the front cover off the engine due to piss poor engine design. Once the cover was off, I discovered the engine has over 0.100” of axial crank float. So out comes the engine. (Easier said than done as it weighs 8000lbs) Crank shaft is toast once I got it out. Thrust surface is chewed out bad. So to say its going well is a understatement. Lmao.

I understand what you are talking about

Whoever cuts zip ties at a 45° ish angle needs to reach around an engine blindly and slice their hand open Then they will never cut them at an angle again

Feeling the pain from the video

Owners seem to think they don't have to do anything but flog their trucks.

So is there a "book rate" for these jobs or is it flat hourly? If you piss away an hour on a customers stripped bolt does that come out of your pocket or theirs?

OMG! U never say what the range of final bill is, but is it over 10K? soooo much time involved.

Hey Ape. I have the master set RBRT torx set from mac tools save my ass alot.

Send a message to cat to mount the ECU to the bottom of the oil pan or could they not find a worse place.

WOW

Do you have a part number for that matco screw extractor set? 😬
